Will, I'm just back from the Nürburgring, and we had a 360 CS in our group. The guy wasn't driving it very hard, so his brakes were still looking ok after a few days. He just had to change the pads. (I think he went to some Pagid.)
This leads me to a little story I just have to tell... My good old 996 Turbo (now with 159'680 km on the clock!) is still able to beat a 360 Challenge Stradale from a rolling start!... We had a little race last Saturday at the Nürburgring's F1-track, and I started in 3rd position, just behind a (modded) Impreza and a 360 CS. Both the CS and I passed the Impreza, and I couldn't believe it, but I passed the CS about 150-200m before the first turn. After a few more turns, everybody was out of sight...

But yep, the CS sounded better...
